Hello,

A fix for this problem was merged recently and will be available in CGAL 
bug fix versions 4.12.2 and 4.13.1 as well as in the next release, CGAL 
4.14 (the beta is already available: 
https://www.cgal.org/2019/03/13/cgal414-beta2/).

See the associated issue: https://github.com/CGAL/cgal/issues/3380, and 
its pull request: https://github.com/CGAL/cgal/pull/3588.

Best,
Mael
